Answer:
Amplitude
Explanation:
The amplitude is maximum height a wave is measured from its rest position.
The position vector of the bullet has components
The bullet hits the ground when , which corresponds to time :
The bullet travels 168 m horizontally, which would require a muzzle velocity such that
Answer: operating large equipment, testing and fixing machinery, recording information, tracking supplies
Explanation:
Answer:
v= 1.71 m/s
Explanation:
Given that
Distance between two successive crests = 4.0 m
λ = 4 m
T= 7 sec
T is the time between 3 waves.
3 waves = 7 sec
1 wave = 7 /3 sec
So t= 7/3 s
We know that frequency f
f= 1/t= 3/7 Hz
Lets take speed of the wave is v
v= f λ
f=frequency
λ=wavelength
v= 3/7 x 4 = 12 /7
v= 1.71 m/s
